Footwear sole



FIG. 1 is a bottom perspective view of a footwear sole;

FIG. 2 is a bottom view of the footwear sole;

FIG. 3 is a top view of the footwear sole;

FIG. 4 is a left side view of the footwear sole;

FIG. 5 is a right side view of the footwear sole;

FIG. 6 is a front view of the footwear sole; and,

The broken lines partially showing a shoe upper throughout the views illustrates the portion of the design that forms no part of the claim. 

I claim the ornamental design for a footwear sole, as shown and described.
